LISTEN TO ME AND COMPREHEND BECAUSE I HAVE TOLD YOU THIS ABOUT THREE TIMES ALREADY AND YOU KEEP TELLING WHAT I JUST OLD YOU WASN'T THE CASE.
When you lose they lose the person they care about most, they turn evil which means, lets say you have a family, but the person you cared about the most was your girlfriend. Your family dies and you get depressed for sure, but then your girlfriend dies and you turn evil.
Sasuke and Itachi did not turn evil because they did not lose the person whom they cared the most about. when Sasuke learned the truth about Itachi and almost went evil for a while was because Itachi was the one he cared most about, however, Itachi came back ans saved him from that fate.
Once again listen sir, pleas. When they lose the person they love most that's when they turn evil Shusui didn't lose Itachi, he died for Itachi and Itachi didn't lose Sasuke either. It's kind of like Mai-Hime, you might lose someone you care about, but you don't lose your powers until the person you love most dies, only you know they turn evil.
Actually yes it does, if you read correctly when the Uchiha lose a loved one it releases a certain type of energy into their brains that activates the sharingan and send them into a despair which causes them go to to extremes and preform evil deeds, basically turning them evil are you going to sit there and tell me that Obito is not evil and that Sasuke wasn't starting to become evil either? Remember the Samurai Prince, they did not deserve that!
They didn't find the spy because the spy was Itachi Genius , they already said that and since we don't know when they found out they were being watched then how do you know that HE provoked them. The Uchiha didn't even start thinking about over throwing the village until after the 4th had died. And still you ignore the fact that Uchiha turn evil when they lose the ones they love most as seen with Madara, Obito and many other Uchiha, even Sasuke was on that path. So see ing as how Tobirama was right to worry about such things, what can you really blame him for other than being careful. Yes he put them in a corner, but he never said that they couldn't roam the village and interact with other people.
We do not know whenthe Uchiha found out they were being watched. It could have been right away and they planned every since or they could have found out near Tobirama's death.
THey could have found out they were being watched during Hiruzen's reign and the Uchiha defeated the spy and used sharigan on him to gather who sent him and the Uchiha would have known that Tobirama sent them
Afterall Tobirama started all of the organization so it is not hard to think of who caused it
He didn't prevoke the Uchiha the Uchiha were just fine until around the time of Danzo, they were not provoked until long after he was dead. Plus even Hashirama agreed that once an Uchiha loses a loved one they turn evil, after all the war and death that had gone on by that time, I'm surprised at what happened anymore.
